Answer:
Mitosis only
Explanation:
Mitosis and meiosis are both types of cell division. Mitosis allows cells to proliferate for growth and repair. So this is how skin cells form new cells.
Meiosis is a type of cell division specific to reproduction. It forms the gametes, which are the egg and sperm. It generates haploid cells that fuse via fertilization to create a zygote.
Answer:
Yes.
Probability of such child = 1/2 or 50%
Explanation:
According to the question, below are the genotypes and phenotypes possibilities:
aa = normal vision & no headache
Aa = normal vision & no headache
AA = blindness & headache
Male Female
Aa aa
Possible genotypes of progeny: Aa Aa aa aa
So it is clear that out of the 4 probable children, 2 with 'genotype aa' will have normal vision & no headache.
Mathematical expression is as under:
2/4 = 1/2 that means 50% progeny.
1/4 if by express you mean in the genotype
1/2 if by express you mean in the phenotype
The female sex hormones are estrogen and progesterone.
Hope that helps!
